摘要

目的：本研究旨在探討於弧形機、減震跑步機與傳統跑步機，對於能量消耗、腰椎與下肢膝關節震盪情形以及髖、膝、踝關節角度之差異。方法：研究對象招募10名大學乙組網球隊選手，進行實驗前，將反光球黏貼於受試者髖、膝、踝關節上。接著將加速規黏貼固定於受試者小腿脛骨內側骨板上與腰部薦椎上，並配戴攝氧量集氧面罩及flow sensor。受試者隨機分配於3台跑步機，並隨機進行慢速(4 km/hr)、中速(6 km/hr)、快速(8 km/hr) 3種的跑步機速度之實驗測試，每次跑5分鐘，組間休息至少10分鐘，統計方法使用SPSS 12.0軟體進行重複量數二因子變異數分析。結果：在弧形機以慢速、中速跑時，著地時膝、踝關節角度與腰椎與膝關節加速度值均顯著小於傳統跑步機與減震跑步機，但在能量消耗值均顯著大於傳統跑步機與減震跑步機。結論：弧形機，不但可以降低腰椎與膝關節的運動傷害風險，在相同運動時間內亦比減震跑步機與傳統跑步機獲得較高的能量消耗。

The purpose of this study was to investigate the differences for the lumbar and knee concussion, and burning calories when running on Curve Walker, Damping Treadmill and Traditional Treadmill. We recruited 10 college division II tennis players as subjects. Firstly, the reflective markers were affixed to subjects’ joints and segments. Then, accelerometers were fixed on subjects’ the tibia bone plate and sacral. Finally, subjects wore a sterile set of oxygen uptake and oxygen mask flow sensor. The subjects were randomly arranged three treadmill testing sequence and three running speeds. The treadmill speeds were slow run (4 km / hr), fast run (6 km / hr), and sprint (8 km / hr). They ran five minutes on treadmill in each condition with at least 10 minutes rest between trials. Statistical processing was using repeated measures two-way ANOVA in SPSS 12.0 software. The results showed that the lumbar and knee acceleration and knee angle that running on the Curve Walker was less than the Damping Treadmill and Traditional Treadmill. The conclusion of this study was that running on the Curve Walker can not only reduce the risk of injury to the knee joint and lumbar spine, and can achieve high energy consumption in a short period of time.
